Problems solved by technology

The electromagnetic flowmeter used in the device in this patent cannot accurately control the purpose of quantitatively outputting a very small amount of slurry within 4-5 seconds
Moreover, the electromagnetic valve of the grout return pipe used in the device in this patent cannot work for a long time in the environment with cement slurry, and it is very easy to reduce the accuracy of grouting due to the wear or damage of the electromagnetic valve.

Embodiment 1

[0031] Such as figure 1 Among them, a metamorphic concrete grouting system, the measuring barrel 7 is provided with a weight sensor 6, the preferred solution is that the weight sensor 6 is a tension sensor, and the measuring barrel 7 is connected to the suspension device 5 through the tension sensor. The suspension device 5 in this example is preferably a chain block, and the advantage of using the suspension device is that only one tension sensor is needed, and the control is relatively simple. It is also possible to adopt the scheme of supporting the measuring bucket 7 on the weight sensor 6 , such measurement and control are relatively complicated, and more weight sensors 6 are required.

[0032] The agitator 3 supplies slurry to the measuring barrel 7 through the first valve 4. The first valve 4 is a manual valve, an electric valve or a pneumatic valve, and a pneumatic valve is used in this example.

[0033] The measuring barrel 7 is connected with the grouting device thr...

Embodiment 2

[0051] Different from implementation 1, an air compressor is not provided in this example, and a generator 1 is provided in this example, and the generator 1 supplies power for the agitator 3, the pump 10 and the vibrator 23;

[0052] A control device 2 is also provided, and the control device 2 is connected to the weight sensor 6 , the vibrator 23 and the pump 10 through a control circuit 26 .

[0053] A wireless receiving module 13 is also provided, and the wireless receiving module 13 is connected with the control device 2 , and the wireless receiving module 13 is also connected with the remote controller 19 in a wireless manner.

[0054] A grouting method using the above-mentioned metamorphic concrete grouting system, comprising the following steps:

[0055] 1. Open the first valve 4, the slurry stirred in the agitator 3 enters the measuring barrel 7, after the weight sensor 6 detects that the slurry weight reaches the set value, the control device 2 alarms, and the first ...

Embodiment 3

[0063] On the basis of Embodiment 1 or 2, there are multiple sets of measuring barrels 7 , pumps 10 and grouting devices, and each measuring barrel 7 is supplied with slurry by the agitator 3 .

[0064] Such as image 3 Among them, two sets are preferred in this example, which can realize two independent grouting processes at the same time and only one operator is required for each grouting operation, and the grouting process can be started and stopped with one key.

Abstract

Disclosed is a distorted concrete grouting system. A weight sensor is arranged on a measurement bucket, a stirrer provides grout for the measurement bucket through a first valve, the measurement bucket is connected with a grouting device through a pump, and a vibrator is arranged on the grouting device. A grouting method adopting the distorted concrete grouting system comprises the following steps that 1, the grouting device is inserted into concrete, a remote control unit is pressed manually, the pump starts grouting, and the vibrator starts vibration; 2, in the process that the weight of cement grout in the measurement bucket is reduced, when the weight sensor detects that the reduction value is the set value, the pump stops, grouting stops, and the vibrator stops vibration in a delayed mode; quantitative grouting is achieved through the steps. According to the distorted concrete grouting system and the grouting method, the self-weighing measurement bucket is arranged, and grouting construction is automatically carried out according to the predefined grout amount.

Description

technical field [0001] The invention relates to the field of metamorphic concrete construction, in particular to a metamorphic concrete grouting system and a grouting method. Background technique [0002] Metamorphic concrete refers to adding an appropriate amount of cement mortar to the roller compacted concrete mixture to make it vibrate, and then vibrating and compacting it with a plug-in vibrator to form a concrete with the characteristics of conventional concrete; in water conservancy and hydropower construction, Roller compacted concrete is often used. It is cement concrete with a low water-cement ratio and zero slump. It is vibrated and rolled by a vibratory roller, and the construction is convenient and quick. However, in construction, some parts cannot be rolled by mechanical equipment. The compactness of concrete in these parts is a problem. If normal concrete is used to pour these parts, the physical properties of normal concrete and roller compacted concrete are ...
